Well, looks like character development is back on the menu for Ortegas, and in a classic Enemy Mine story. Not convinced it needed the tie-in to the original series, and the excuse they've finally come up with for "why do our Gorn look different?" is about as lame as it could be. That aside, pretty good episode.
I like how Starfleet's survival paradigm is Water, Food, Shelter, because they know the chances of anyone being marooned somewhere without a breathable atmosphere in this setting are vanishingly remote - not even if it's a barren rock whose orbit drags it through a gas giant's atmosphere every rotation.
